This site claims: "For over thirty years, he has been studying, modelling, building and testing his own ornithopter — an invention that was first conceived some five hundred years ago, but is yet to be implemented successfully." This is so falsely absurd I am not sure where to begin. Many ornithopters have been constructed that flew or fly successfully; there have even been a few successful full-scale attempts. Most were models, though. A recent model implementation: https://www.kickstarter.com/projects/274008848/metafly-a-new-flying-experience https://www.kickstarter.com/projects/274008848/metafly-a-new... ...which was inspired by a much older toy - which itself (if we're being honest) was probably based off of even older examples: https://en.wikipedia.org/wiki/Ornithopter https://en.wikipedia.org/wiki/Ornithopter Then you have Paul MacCready's Pterodactyl: https://en.wikipedia.org/wiki/Paul_MacCready https://en.wikipedia.org/wiki/Paul_MacCready I won't go on...
